peroneal nerve injury caused by popliteal block

Knowledge of variant anatomy of the sciatic nerve is important in avoiding inadvertent injury during operations in the gluteal region and interpreting nondiscogenic sciatica. This variant anatomy may cause piriformis syndrome and failure of sciatic nerve block. The variations differ between populations but data from Africans is scarce. This study, therefore, investigated variations of sciatic nerve in a black Kenyan population. One hundred and sixty-four sciatic nerves from 82 cadavers of black Kenyans were exposed by dissection at the Department of Human Anatomy, University of Nairobi, Kenya...
